1. Divide the number repeatedly by 2:
Keep track of each remainder.
Stop when you get a quotient that is equal to zero.
- division = quotient + remainder;

2. Construct the base 2 representation of the positive number:
Take all the remainders starting from the bottom of the list constructed above.
3 043 961 713 799 183(10) = 1010 1101 0000 0111 0111 1001 0000 1010 1001 0011 0000 0000 1111(2)
3. Determine the signed binary number bit length:
The base 2 number's actual length, in bits: 52.
- A signed binary's bit length must be equal to a power of 2, as of:
- 21 = 2; 22 = 4; 23 = 8; 24 = 16; 25 = 32; 26 = 64; ...
- The first bit (the leftmost) indicates the sign:
- 0 = positive integer number, 1 = negative integer number
The least number that is:
1) a power of 2
2) and is larger than the actual length, 52,
3) so that the first bit (leftmost) could be zero
(we deal with a positive number at this moment)
=== is: 64.
4. Get the positive binary computer representation on 64 bits (8 Bytes):
If needed, add extra 0s in front (to the left) of the base 2 number, up to the required length, 64.
